Version 1.21 or earlier:
Remove the folder "Army 101AD_LaPointe" prior to installation.

Version 1.02 or earlier:

DCS World 1.2.7 changes the pilot and gunner texture files, so the textures have been updated accordingly in this file. In order to clear out the obsolete files, go to the individual folders and remove the following files:
Gunner_UH1_*.dds
Pilot_UH1_USMC.dds

Installation:
Copy the folders (except for TempTextures; see below) to your Liveries\uh-1h folder (either in DCS World\Bazar or Saved Games\DCS).

Optional:
I have included files that have (IMHO) improved the textures of the pilots and door gunners. They now wear the standard green and grey nomex flight gloves and have pencil pockets on their left sleeves, similar to my USN and USMC uniform textures. Additionally, I included a 1st Cavalry patch that blocks the alpha channel for the First Sergeant rank, which removes sleeve rank insignia from the gunners' flightsuits (enlisted folks in the US services don't wear rank insignia on flightsuits).

To enable these textures, just copy the contents of the _Optional\TempTextures folder to your DCS World\Bazar\TempTextures folder. To disable the textures, just delete them from TempTextures and the default textures will be used instead.

Optional:
The release of DCS World 1.2.4 added the ability to add texture paths using the file "autoexec.cfg" in your Saved Games\DCS\Config folder. This will allow you to save hard drive space as long as the skin filenames are unique. My skins support this, so any DDS file with the same name will be identical.

In order to enable this feature, add the following line to autoexec.cfg (be sure to create the file if it doesn't exist):

You can use any path (even a different drive), but you must use forward slashes for your path. Backslashes won't work here.

Then, you can move all of the DDS files from each of the skin folders to this new folder you've added to your path. Allowing overwrites is not a problem, as I use unique names for each file. Finally, be sure to go in to each description.lua file and change all "false" entries to "true."
